Application filed June 21, 1912. Serial No. 705,045.

To all whom it may concern q Be it known thatv I, Liiz in Lumios, a subject of the. King of-Hungary, and resident of the city of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Combination Steam-Boilers and Water-Heaters, of which the following a s ecification.

heaters and vaporizers, and has for one of its objects to provide a simple and inexe generation of steamandfor heating water,

for instance for bathingywashingor other purposes. The steam generated maybe conducted to-radiators, etc. With these and other objects in- View,

which will morev fully appear asthe nature of the invention is better understood, .the

ment and construction-of parts hereinafter fully described, pointedout in the. appended drawings, changes may be made in the SlZ and proportion of the several parts and minor details of construction within the scope of the.

appended claims without departing from the spirit or sacrificing any'of the advantages of the invention. One of the many possible'e'mbodiments of the invention is illustrated in the accompanying drawings, in which i Figure, 1 is a central longitudinal section taken througha combined steam boiler and water heater constructed in accordance with the present invention Fig. 2 is-a frontelevation of the same; Fig. 3 is a section taken on line3-3 of Fig. 1; and Fig.4; is a section taken on line P of Fig. 1.

In the drawings, thenumeral 5 indicates the, preferably, cylindrical boiler shell,

.' which is provided withih'eads 6 and 7., The

whole structure is adapted to rest on' legs or standards 8, 8. The shell -1s rovided with a longitudinal partition 9, divlding the same into compartments 10 and 11 which do 'not communicate with 'each other. In the lower portions of each of these compartalso be made cylindrical, as clearly shown In Fig. t of the drawings. Near. the bottom of each fire-box is supported a grate 13 on which fire may be built. Below these grates 1 shell to the, fire=boxes 12. he present invention relates to liquidare located the ash-pits l t, to which access may be had through collars 15, the outer ends of which extend beyond the cylindricalshell 5, and are provided with dampers16, 1 6, which arev hinged at 17 to d0ors..'18 are provided, which are hinged M 19 to collars 20, extending through the The two fire boxes communicate with each other through altubu'lar memberv 21, which extends through the partition 9 and contains a disk valve 22,

:WhiCh iis-adapte'd to befactuated by means of a handlev23, the latter being attached to the spindle 24' 'ofthe valve. By means of this valve the communication between the two fire-boxes may be controlled for a purpose hereinafter to be.deshribed-. From the top of each'xfi-re-box extends a flue' 25,

extending uptbward and to the head 6 and "the c01lars15. :F or .the' admission of fuel,

through the: said head, to beconnected with thech-imney. The fiues which serve to conduct theheated air and products of combustion toward the chimney are bent in the form ofcoils. .Obviously the flow of the products of combustionwill thereby be re 'tarded-and their. heat effectively given up to the water that surrounds the said flues and the fire-boxes in the compartments. In each flue there is arranged a damper 26 of the well known construction, adapted to be operated manually to control the draft in The compartment 11 forms .the water heating section of the device, the water enbottom and with a steam pipe 30: in the head 6. The normal Water level is indicated by the line denoted by the numeral 31, the height of the water within the boiler being indicated by a water-gage .32 of any suitable construction. To indicate the pressure of steamjin the boiler, a steam gage 33 may be provided, and a safety valve 34 maybe made use of for preventing the pressure of the steam from exceeding a certain predetermined point-.-., The damper 16 of the compartmen-t 10 may be set byhand, or it vmay be "*a-ctuated automatically through the compartments of the shell.- W'ater, ad;

"supply pipes 27 and 29, rises in the coma 7 is, however entione that-the 'damper '16. thereof is c osed by the steam pressureas combustlon will escape through bothlflues connected by the intermediary of avplurality damper. "The particular Construction of the 'In cold-weather, when both-hot water and used. In the boiler-compartment the water automatically' to an extent proportionate heating the water at e "heater compartsteam pressure by a mechanism '35, which is of levers 36' and a rod 37 with the said mechanism 35 need not be described, as the same does not form-an essential part of the invention. I The operation of this device is as follows:

steam are used, fire is placed into both fireboxes 12, 12. The valve 22 is set to open a, communication between the-two fire-boxes so" as to equalize the temperature in the two mitted to the two compartments through the partment 11 up to its top, and is to'be shut off as soona'sitrise's to the height indicated; by the line-31 in the steam'boiler compartment. The water; the heater compartment. 11 surrounds entirely the fire-box and the coiled flue, and will be thus quickly and economically heated, to be conducted through the pipe 28 to the place at which it is to [be is converted into. steam and conducted through the pipe 30 to radiators or otherplaces. The' .operation ofzthe several at tach'ments .of theboiler compartmentneed not be described-as the are well known. It

the same exceeds the normal, and is opened .to the decrease of pressure in the boiler;

If mainly steam is needed. the fire-box" in the compartment .10 is only fired, the' valve 22 being-left open so that the products of of the device, generatih thereby'stie am' and Copies of this patent may be 'obtadnedw ilve cents ment. If only hot water is' needed, the

'valve 22 is closed and fire is placed only in the fire-box which is arranged within the compartment 11.

What'I claim is: (1. In a device'of the character described, the combination with a boiler divided by a longitudinal 'partition into two non-com- I municatingcompartments,- of a water supply pipe leading to each compartment, an'

outlet pipe also connected with each compartment, a, fire-box arranged within each, compartment, and a flue in theform ofa coil extendin through each compartment and connected to each respective fire-box.

2. In a device of thecharacter described",

the combination with a boiler divided by a longitudinal partition; into two non-communicating compartments, of a water supply pipe leading :to each compartment, an outlet pipe also connected with each compartment, a, fire-box arrangedwithin each vcompartment, said two fire-boxes communieating with each other, a valve adapted to control said communication, and a flue in the form of a coil extending through each compartment vand connected to eachrespect'ive fire-box. I e

3. The combination withfa shell forming a hot-water heater, of afirebox arranged each, by addressing the Commissioner of fi -*2 Washington, D. 0.
